We see where you are going, but "different enough" sounds like
something related to our contrast measures. The problem is that if the
colors are different enough to meet the contrast requirements, then
they can't both meet the contrast requirements with the background. We
don't have any data to specify 'different enough' other than our
contrast ratio (which can't be used per the previous sentence) so we
don't treat it here. If data comes in later that we can use, we can
add other sufficient techniques to reflect it.
